285 vs 305 Tires
The main difference between these tire sizes comes down to section width. The 305 tire size is 20 millimeters (0.79 inches) wider than the 285 tire size. This slight difference in width impacts various performance factors.
305 vs 285 Tires
By referring to this comparison table, you can quickly grasp the differences between the two tire sizes and better understand their distinctive features.
| Feature | Tire Size 285 | Tire Size 305 |
|---|---|---|
| Width (mm) | 285 | 305 |
| Width (inches) | 11.22 | 12.01 |
| Width Difference | 20 millimeters smaller than 305 tire size | 20 millimeters larger than 285 tire size |
| Ground Clearance | Slightly lower | Slightly higher |
| Gas Mileage | Slightly better | Slightly worse |
| Ride Comfort | Smoother on pavement | Better impact absorption off-road |
| Aesthetics | Balanced look | More aggressive stance |
| Handling | More responsive | Added stability |
| Noise Levels | Bit quieter | Dampens vibrations slightly better |
| Durability | Comparable | Comparable |
| Adverse Conditions | Better Traction on ice/snow | Better Traction in mud/sand |
Ground Clearance
The slightly wider 305 tire provides a slight increase in ground clearance over the 285, which is beneficial for off-roading.
However, the difference is minor, and both can potentially scrape on obstacles. Lower profile 285 tires offer more straightforward speedometer calibration.
Gas Mileage
With a more minor contact patch, 285 tires confer improved fuel efficiency over 305. The marginally lighter rotational mass also contributes to better gas mileage. However, the difference is modest, and both remain reasonable options for commuting.
Ride Comfort
On smooth roads, narrower 285 tires provide a smoother ride, while wider 305 absorb impacts slightly better on uneven surfaces. Overall ride comfort differs minimally between these two sizes.
Aesthetics
305 tires lend a somewhat brawnier, aggressive look, especially on trucks and SUVs. However, 285 maintain a well-balanced aesthetic on most vehicles. Beauty remains subjective with either size.
Handling & Stability
More responsive steering and handling gives 285 tires a slight edge on the pavement. But 305 offer somewhat more stability and traction off-road. On most roads, both handle well with no major difference.
Noise & Vibration
With less tread in contact with the road, 285 tires are marginally quieter on smooth pavement. But 305 can dampen vibrations slightly better. Neither produces excessive noise or vibration.
Durability & Wear
The nearly identical sizes offer comparable durability and treadwear. Both should provide many miles of use with proper maintenance. Rotating and aligning them regularly optimizes longevity.
Adverse Conditions
In deep mud or sand, wider 305 tires gain a bit more traction over 285. But on snow and ice, 285 can cut through slightly better. Overall, the small size difference minimally impacts performance in adverse conditions.
Difference Between 285 and 305 Tires
The main difference is the section width, with 305 tires being 20mm wider than 285 tires. This affects various performance aspects such as grip, handling, and fuel efficiency.
Can I Use 285 Tires Instead of 305?
Yes, it’s possible to use 285 tires instead of 305. The rim width ranges overlap, making it a suitable change. However, ensure the aspect ratio and rim diameter match your current setup. If not, keep the overall diameter difference within 3% to maintain vehicle performance.
Can I Use 305 Tires Instead of 285?
Yes, you can use 305 tires instead of 285. Their rim width ranges overlap, allowing for this change. Remember to match the aspect ratio and rim diameter with your current setup. If they differ, keep the overall diameter difference within 3% to avoid affecting vehicle performance.
Can I Put 285 Tires on 305 Rims?
Yes, you can put 285 tires on rims designed for 305 tires. The ideal rim width range for 285 tires (9.0-10.5 inches) overlaps with the range for 305 tires (9.5-11.0 inches), ensuring proper fitment and performance.

Our Observation
While 305 tires offer some advantages for off-roading, 285 provide slightly improved on-road manners. For most drivers, the difference between these sizes remains minor.
Those seeking an aggressive look may prefer 305, but 285 blend well aesthetically with most vehicles. Either size works well for optimal longevity, fuel efficiency, and a smooth, comfortable ride. Evaluate your priorities and weigh the trade-offs, but you can go right with a 285 or 305.
